Abstract
A lubricating composition is provided containing: a high viscosity synthetic hydrocarbon such as high viscosity polyalphaolefins, liquid hydrogenated polyisoprenes or ethylene-alphaolefin copolymers having a viscosity of 40-1000 centistokes at 100° C.; a low viscosity synthetic hydrocarbon and/or optionally a low viscosity ester; and optionally an additive package to impart desirable performance properties to the composition.
Claims
exact text as granted — not AI-modifiedWe claim:
1. A lubricating composition comprising: (a) between 1 and 99 weight percent, based on the weight of components (a), (b) and (c), of a polyalphaolefin having a viscosity of between 40 and 1000 centistokes at 100° C.; (b) between 0 and 99 weight percent, based on the weight of components (a), (b) and (c), of a synthetic hydrocarbon having a viscosity of between 1 and 10 centistokes at 100° C.; (c) between 0 and 99 weight percent, based on the weight of components (a), (b) and (c), of a carboxylic acid ester having a viscosity of between 1 and 10 centistokes at 100° C.; and (d) between 0 and 25 percent by weight of an additive package; wherein at least 1 weight percent, based on the weight of components (a), (b) and (c), of component (b) and/or (c) is present.
2. The composition of claim 1 wherein component (a) has a viscosity of between 60 and 1000 centistokes at 100° C.
3. The composition of claim 1 wherein component (a) is a polymer of a member of the group of monomers consisting of octene-1, decene-1 and dodecene-1.
4. The composition of claim 3 wherein component (a) is poly(decene-1).
5. The composition of claim 1 wherein at least 1 weight percent, based on the weights of components (a), (b) and (c), of component (b) is present.
6. The composition of claim 1 wherein at least 1 weight percent, based on the weight of components (a), (b) and (c), of component (c) is present.
7. The composition of claim 1 wherein at least 1 weight percent, based on the weight of components (a), (b) and (c), of components (b) and (c) is present.
8. The composition of claim 7 wherein component (a) has a viscosity of between 60 and 1000 centistokes at 100° C.
9. The composition of claim 7 wherein component (a) is a polymer of a member of the group of monomers consisting of octene-1, decene-1 and dodecene-1.
10. The composition of claim 9 wherein component (a) is poly(decene-1).Cited by (0)
